The Long Āgama Sūtra 6.32

6.32

佛告比丘：「我今遍觀諸有力者無過魔力，然漏盡比丘力能勝彼。」爾時，諸比丘聞佛所說，歡喜奉行。

The Buddha told the monks, “Now, I’ve surveyed all those who possess power, and none surpass the power of Māra. Still, the power of a monk who ends the contaminants can defeat him.”

The monks who heard what the Buddha taught rejoiced and approved.
